Decision shaping neutrophil-platelet interplay in inflammation: From physiology to intervention.

Inflammation is a well-coordinated process in response to tissue injury or infection aimed at restoration of tissue homoeostasis. Platelets and neutrophils are typically viewed important in the context of haemostasis and bacterial killing, respectively. However, as these cells are equipped with readily available armoury, both have received much attention for their importance in shaping the early inflammatory reaction in recent years. While some of these activities are executed individually, both cells join forces during much of their pro-inflammatory activities. This brief review summarizes recently identified mechanisms of neutrophil-platelet interaction and describes functional consequences on neutrophil trafficking and the release of neutrophil extracellular traps. Moreover, the synergy of neutrophils and platelets during the recruitment of monocytes is reviewed. Finally, this review discusses how knowledge on the intimate neutrophil-platelet partnership can be employed to design interventional strategies.
